Jeon Jungkook, the ruler of the North who came back from the war.
The man, who was perfect in everything, was the only good memory of Lalisa's unhappy childhood.
When she was told that he was going to be her husband, Lalisa believed in the existence of God for the first time.
But...
"If there's anything you want, feel free to do it. It doesn't matter whether you remodel the castle, buy jewelry, or throw a party."
"......."
"But I don't want to see you in the morning, so refrain from doing that."
The gentleman of her memory was no more.
There was only a cold man standing there who did not have a trace of affection or warmth.
"Your heart is of no use to me."
But loving him to the end was Lalisa's biggest mistake.
